Summary
Short stems for hip replacement surgery are gaining popularity for less invasive procedures. Initial results show no revisions for loosening in 500 patients using this bone-conserving approach.
Area of Science:
- Orthopedic Surgery
- Biomedical Engineering
Background:
- Increasing interest in minimally invasive total hip arthroplasty (THA).
- Short stems offer potential bone-conserving benefits.
- Curved broaches and stems facilitate insertion via a curved track, avoiding abductor muscle attachments.
Purpose of the Study:
- To report initial clinical experience with a new short stem design for THA.
- To evaluate the early outcomes of the Fitmore short stem.
Main Methods:
- Prospective study involving 500 patients undergoing THA.
- Utilized a new short stem design (Fitmore, Zimmer Orthopedics).
- Surgical technique involved curved broaches and stems for insertion.
Main Results:
- No stems required revision due to aseptic loosening in the initial cohort.
- The short stem design allows for higher neck retention.
- Maintenance of the medial greater trochanter and preferential stress transfer to the proximal femur were observed.
Conclusions:
- The initial experience with the Fitmore short stem in 500 THA cases is favorable.
- The short stem design appears to be a viable bone-conserving option for THA.
- No aseptic loosening was observed, suggesting good initial fixation.
